Title: Add extra "checkbox" class to label with nested style enabled using :label_input in wrapper config.

Should close close #428 with wrapper

```ruby
config.wrappers :checkbox, :tag => 'div', :class => 'control-group', :error_class => 'error' do |b|
b.use :tag => 'div', :class => 'controls' do |ba|
ba.use :label_input
end
end
```

```slim
= form.input :remember_me, \
as: :boolean, \
label: 'Remember my login on this computer', \
wrapper: :checkbox
```
